Abstract

An appliance (10) for disinfecting contact lenses (24) wherein the lenses are disposed within a disinfecting solution (28) which liberates gas (A) during the disinfecting action, includes a container body (12) for immersion of the lenses within the disinfecting solution (28) and a removable cap (14) closing the container body (12). The appliance further includes a normally closed vent conduit (30, 42) for passage of the pressurized effluent gas (A) from the container body (12) through the cap (14), and within the vent conduit is a check valve (32) including a disc member (34) having a slit (36) therethrough which opens for vent discharge of the gas (A) with sufficient pressure on the disc exerted by the gas during passage through the vent conduit, after which the slit (36) recloses to prevent any subsequent leakage of the solution (28) therethrough.
